Backend:
- Prisma: add stripeSubscriptionId, subscriptionStatus, priceId,
currentPeriodEnd to User + migration SQL
- plugins/stripe.ts: getPlans catalog with env-based price IDs

skip rate limit on /stripe/webhook

- POST /stripe/checkout hosted Checkout Session, lazy-creates
customer, dynamic payment methods, promo codes enabled
- POST /stripe/portal Billing Portal session
- POST /stripe/webhook signature verified, handles
checkout.session.completed, customer.subscription.*,
invoice.payment_failed. Resolves user by clientReferenceId,
metadata.userId, or stripeId fallback
- .env.example + README: Stripe setup, stripe CLI, test cards
Frontend:
- api/stripe.ts typed client (getPlans, getSubscription,
